is there a an 82 gsl-se?
 

a guy on craigslist was posting a posi rear end from an 82 rx7 gsl-se , and i do want posi for my rx7 . but i thought gsl-se where only made in 84 and 85 ? please correct me if i am wrong thangs .

Yes you are wright there is no 82 gsl-se they started in 84.

its probably from an '82 gsl, which had limited slip diffs as well.

Yup. Limited slip (with rear disc brakes) was standard equipment on all '81 through '85 GSLs. The SE models (only produced in '84 and '85) also came with both LSD and rear discs, but the final drive ratio was slightly different --- on the order of 4.09 vs. 3.95 for the GSL. The SE brake discs were also bigger and vented, where the non-SE models had smaller and solid discs.

Yes, like everyone was saying it is a gsl I'm sure.

The 81-85 gsl's had a 3.909 rear end

The 84 GSL-SE had a 4.083 rear end

The 85 GSL-SE had a 4.077 rear end

My gsl-se I think has a solid rear disk just like a gsl but the front is for sure vented rotors. And of corse the gsl-se's had the 4x114.3 lug pattern instead.

He probally did not know for sure what he has. Someone could have put a gsl-se emblem on the rear of that car or he could have the year wrong. I guess the only way for sure to know would be to count the revolutions on the rear.

yes you want posi


hey chad nevermind about the lift to K.C. my buddy and me are making the trip next weekend

Are you sure? My gsl front discs are vented.:confused:

It is the rear that are solid on the gsl. The front are vented. The GSL-SE are vented all around.

no such animal
 

if you want posi just weld the spider (pinion) gears in your final drive (rear), works like a charm just dont speed around courners with posi as it will spin your ride like a top, mybe even flip your ride. posi only good for the straight line. :rock:

Ok, ya next weekend would be bad anyways.
Try to get him to meet you closer.

Ummmm, you're joking, right?

Welded spiders are not the same thing as a posi. A posi will slip to allow you to take corners, where as welded spiders will not.

a true posi is the same thing as welding the spiders. they're several different types of rearend set-ups

1.open diff =suck

2. limited slip(lsd) usually has clutch packs or cone with springs to provide friction. will allow tires to spin at different speeds when turning but provides good straight line acceration. this is what most car companies use as an upgrade

3. positive traction units(posi). these connect the axles together solidly all the time and do not allow them to turn at different speeds.this makes street driving kinda hard and sometimes dangerous.
ghetto posi.when somebody welds the spider gears in an open diff together. no exactly the best move,cant be reversed easily,if not done right it could break.

True, but cheap, and gets the job done...

Can also have gears (Torsen) or be fluid filled coupling (Viscous) Each has pros and cons.

Can also be called a Locking axle because of how they act on wheelspin.

No.

That'd be called a spool (Because it looks like what thread comes on.) or a non differential solid axle. Welded axles can be called "Lincoln Locker" and other brand names of welders have been used in that term as well.

"Posi-Traction" is a term that GM used to use to talk about their Limited Slip Differentials (LSD's)... It has since become such a commonly used term that it's used to talk about all LSD's...

For instance, you need a page from a book at the library, do you make a Xerox, or photocopy?

You have a cold. Do you blow your nose on a Kleenex or a tissue?

You slice your hand up. Do you close the wound with a Band-Aid or an adhesive medical strip.

No car made from the 60's up till present would have a non differential axle. I'm not sure when the differential was invented, but I'm sure it would be incorperated on any modern, street driven car.

Search turned up this. It's been in use since the 1800's and on Steam driven cars.
